Having the right tool for the right job is not always possible, but it’s an ideal that’s nice to try to live up to. The problem is that a lot of the time, the right tool is often very expensive. We have found lots of ways around this, though, from building our own CNC machines to finding new ways to electroplate metal. Sometimes, though, the right tool for the job doesn’t have to be improvised or built from scratch, it just falls in your lap.

Admittedly, [Sam]’s power planer didn’t literally fall into his lap, but he did pull this …read more http://pje.fyi/PgjBZb

We can all use a little more green energy in our lives at home. So when [ahmedebeed555] — a fan of wind power — ran into durability troubles with his previous home-built turbine, he revised it to be simpler than ever to build.

Outside of the DC generator motor, the rest of the turbine is made from recycled parts: a sponge mop sans sponge, a piece from an old CD drive case acting as a rudder, the blades from a scrapped fan, and a plastic bottle to protect the motor from the elements.

The problem is that when the sun is up, hikers are on the move – not very conducive to deploying a solar array. The Wind, however, blows all through the night.
